A Bad Day for Sir Handel is the sixth episode ever made in Season 4.
Peter Sam and Sir Handel arrive on the Skarloey Railway. Peter Sam is kind, but Sir Handel is bad-tempered and insults Skarloey and the sheds. The next day, Sir Handel is chosen to pull the train to the top station. He does so grudgingly, and, after insulting the coaches by calling them "cattle trucks" and surprising Gordon with his knowledge of coaches, makes his way to the top station. There, he is cross to discover he is expected to go to the quarry and collect trucks, and refuses to do so, punctuating his point by deliberately derailing himself. In the end, Peter Sam helps Sir Handel back on the rails and the Fat Controller puts Sir Handel in the shed as punishment.
- When Sir Handel and Peter Sam first arrive, Percy is passing with a train of trucks. However, when Sir Handel looks at Skarloey, Percy is reversing for some reason, and a tar wagon has joined his train.
